Description
Hello,
tried to union the marked obejcts in a vector layer. The function start and near 98% done, qgis crash.
When I reduce the amount of the marked objects, function show 100% is done, but when I will save the changes in the layer, qgis crash.

Fixed in r12673. QGIS now shows a message box if there was an error in the merge operation (instead of crashing).

Thanks Marco.
I noticed that the "check geomtery validity" tool does not returns any topology error when used in the attached vector. This way the user has no clue why the merge fails.

Hello,
Befor I opened this new ticket, i had first tested the attached vectorlayer also with ftools "check geometrie" and it was ok.
The problematic object in the layer seems to be nr 97 (97 in the dbf, field NR.)You can`t merge it with other objects.
